2.2.3 Emission Requirements
According to the EMC product standard for adjustable
speed frequency converters EN/IEC 61800-3:2004 the EMC
requirements depend on the intended use of the
frequency converter. Four categories are defined in the
EMC product standard. The definitions of the 4 categories
together with the requirements for mains supply voltage
conducted emissions are given in
.
Category
Definition
Conducted emission requirement
according to the limits given in EN

C1
Frequency converters installed in the first environment (home and office) with a
supply voltage less than 1000 V.
Class B
C2
Frequency converters installed in the first environment (home and office) with a
supply voltage less than 1000 V, which are neither plug-in nor movable and are
intended to be installed and commissioned by a professional.
Class A Group 1
C3
Frequency converters installed in the second environment (industrial) with a supply
voltage lower than 1000 V.
Class A Group 2
C4
Frequency converters installed in the second environment with a supply voltage
equal to or above 1000 V or rated current equal to or above 400 A or intended for
use in complex systems.
No limit line.
An EMC plan should be made.

2.2.4 Immunity Requirements
The immunity requirements for frequency converters
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and office
environment. All Danfoss frequency converters comply
with the requirements for the industrial environment and
consequently comply also with the lower requirements for
home and office environment with a large safety margin.
